Title: Sample agglutination test - in diffusion separators of centrifuge based on optical density
Inventor: SZABO ZSOLT DR
IPC: G01N33/49
Filed: 1989-07-28
Abstract: An automatic agglutination reaction is performed in the diffusion separator of a centrifuge using a reation mixt. of suspension and serum.  The optical density of the sample is determined continuously. If there is a point of inflexion in the transparency curve, this point is joined to the origin to form a reference curve.  If the max. deviation from this curve is more than 30% transparency, this is taken as proof for the absence of agglutination. ADVANTAGE - This is a particy. suitable process for the performance and evaluation of slight agglutination reactions which prevents contamination of the inside wall of the separator.  (10pp
